In what year did Charles Coulomb discover Coulomb's law?

Explanation:
Coulomb’s law was established from experiments that used a torsion balance to measure the electrostatic force between charges, showing that the force is proportional to the product of the charges and inversely proportional to the square of the distance between them. He published these results in 1785, the year associated with the discovery of the law. The other years do not reflect the date of his publication, so 1785 is the correct year.
